However, after some super-sleuthing we can confirm Lachy DID NOT double tap the post.

Not done with her Cat Day celebrations, Emma also took to her Instagram Stories to show a video of her singing to her and Lachy's cat Basil, making sure she once again tagged her former partner.

In a joint statement last Friday, the pair explained what their separation would mean moving forward.

"We have, and continue to share, the most beautiful life together, but we wanted to let you know that privately for the last six months we have been navigating through a trial separation, and we have made the decision to separate as a couple," the stars said.

"Throughout that period, we have performed hundreds of shows together and that is always a continued source of joy for us both."

"We have embraced this as a very positive change in our relationship. Our incredible friendship has been strengthened throughout this time and what we have discovered is that, more than ever, first and foremost we love and adore performing as Emma and Lachy in The Wiggles and having the privilege of celebrating this happiness with extraordinary families around the world."

"We have chosen a different path to travel in our personal lives, but please know that we are stronger than ever and we can't wait to see you at a show soon. We will not be commenting beyond this, and we thank you in advance for respecting our privacy," they concluded.

Lachie is taking it hard

In reports over the weekend, friends of Lachie told Sunday Confidential that the purple Wiggle has been left feeling blue as the relationship fell apart.

"Lachy is absolutely heartbroken," it is reported.

The source went on to say: "He was completely besotted by Emma and worshipped her and still does.

"He tried everything to make it work, but in the end, he couldn't. His heart has been broken."

Emma and Lachy's love story had become one of the nation's most treasured fairy tales after the children's entertainers fell in love working on the popular super-group.
